When I checked the log Located $ORACLE_HOME/SID_HOSTNAME/sysman/log
I found the below errors :
app.ContextInitializer contextInitialized.420 – Integration Class not found
and
ERROR main: nmectla_agentctl: Error connecting to
First you need to make sure that the link in emd.properties and ports and configured right and hostname is correct, restrat dbconsole if this not works then check the below
On Host :
oracle@TEST:/u01/app/$ echo $TZ
localtime
oracle@TEST:/u01/app/$ export TZ=Etc/GMT+2
emctl config agent updateTZ
emctl resetTZ agent
Restart Dbconsole
Emctl start dbconsole
Thank you
